Evolution Aqua have launched the Nexus320+ and Nexus220+ filtration systems. Building on the tried and tested technology that has been ever present in the world renowned Nexus, the team at Evolution Aqua have gone even further to enhance their number one Koi pond filter.

The Nexus320+ and Nexus220+ filters now come with a new filter media called K+Media in the moving bed outer chamber for vastly improved biological filtration and faster filter maturation. The new Nexus+ filters are also supplied “auto ready”, with factory fitted fixings already in place, making it even easier to upgrade to the Nexus Automatic Cleaning System.

OVERVIEW OF HOW THE NEXUS+ WORKS

The Nexus+ filter is an innovative biological and mechanical filter system in one. Water enters the Nexus+ via the inlet into the inner chamber which forms as a vortex allowing larger solids to settle out. The water then passes through the Eazy where the finer particles are removed at the mechanical stage of filtration. From the Eazy the water passes into the outer chamber where the biological stage of filtration takes place using the new K+Media Moving Bed.

The water then passes through the grill into the Exit Chamber, where it is returned to the pond through the outlet. The Eazy is cleaned by diverting the air from the Outer Chamber to the Eazy using the air valves or by installing the automatic cleaning system which makes the cleaning process even easier, as the filter can be cleaned even when you’re not there.

Nexus+ filter systems can be easily installed on gravity-fed or pump-fed set ups.
